Ok. This requires the notion of "intrinsic value", which I believe does not exist (all value is subjective), yet is a foundation of all Marxist theory.
Why "terminate", Marxist philosophy is a legitimate topic, deserving to be studied. Like a rich sci-fi lore or a history of Tarot magic. Deep, fascinating, and wrong.
And yet you terminated. Which would be the correct thing to do if Marxist philosophy would be wrong on all counts, as you explicitly state. Which of course, it isn't.
